Press release date: May 10, 2012

SUMMARY
Heat-Away(TM) 641-EV, a new high temperature, electrically and thermally conductive, vacuum compatible, silverfilled grease developed by Aremco Products, Inc., is now used in heat transfer applications from -60 to 550 °F (-51 to 288 °C).

FEATURES
Heat-Away(TM) 641-EV is a single-part, 100% solids, silver-filled, electrically and thermally conductive, vacuum compatible grease used in heat transfer applications from -60 to 550 °F (-51 to 288 °C). Heat-Awaytm 641 is formulated as a thick paste that will not flow after application and the viscosity will remain stable over the entire temperature range. The thermal conductivity is 5.58 W/m-K and resistivity is less than 0.0008 ohm-cm. The vapor pressure is 3 x 10-14 at room temperature and 2 x 10-6 at 200 °C

Heat-Away(TM) 641-EV is used to improve the thermal transfer between heaters and process vessels and various heat sinks used in heat exchangers and electrical and electronic applications. Heat-Away(TM) 641-EV is supplied in standard 50-gram kits from stock and larger containers upon request.
